Chrysanthemum plant named ‘Yopueblo’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yopueblo’, characterized by its upright, outwardly spreading and uniformly mounded plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored foliage; uniform, freely and early flowering habit; daisy-type inflorescences with orange bronze-colored ray florets and green-colored disc florets; and excellent postproduction longevity.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yopueblo’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a pot-type Chrysanthemum and hereinafter referred to by the name ‘Yopueblo’.

The new Chrysanthemum is a product of a breeding program conducted by the Inventor in Fort Myers, Fla. The objective of the breeding program is to create new pot-type Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, freely branching habit, good vigor, desirable inflorescence form and floret colors, fast response time and excellent postproduction longevity.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in January, 2004, in Salinas, Calif. of a proprietary selection of Chrysanthemum×morifolium identified as code number YB-A4929, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number YB-A3803, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Fort Myers, Fla. in March, 2005.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in a controlled greenhouse environment in Fort Myers, Fla. in June, 2005. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yopueblo’. These characteristics in combination distinguish ‘Yopueblo’ as a new and distinct pot-type Chrysanthemum cultivar:

-   -   1. Compact, upright, outwardly spreading and uniformly mounded         plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored foliage.     -   5. Uniform, freely and early flowering habit.     -   6. Daisy-type inflorescences with orange bronze-colored ray         florets and green-colored disc florets.     -   7. Excellent postproduction longevity with inflorescences         maintaining good substance and color for about four to five         weeks in an interior environment.

Plants of the new Chrysanthemum differ from plants of the female parent selection primarily in plant habit as plants of the Chrysanthemum are more upright than plants of the female parent selection. In addition, plants of the new Chrysanthemum have stronger stems than plants of the female parent selection.

Plants of the new Chrysanthemum differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are shorter than plants of         the male parent selection.     -   2. Plants of the new Chrysanthemum and the male parent selection         differ in ray floret color as plants of the male parent         selection have red-colored ray florets.     -   3. Plants of the new Chrysanthemum do not produce pollen whereas         plants of the male parent selection produce pollen.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Yoauburn’, disclosed in U.S. Plant Pat. No. 12,526. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum primarily from plants of ‘Yoauburn’ in the following characteristics:

-   -   1. Inflorescences of pants of the new Chrysanthemum had a larger         disc than inflorescences of plants of ‘Yoauburn’.     -   2. Plants of the new Chrysanthemum and ‘Yoauburn’ differed in         disc floret color as plants of ‘Yoauburn’ had bright         yellow-colored disc florets.     -   3. Plants of the new Chrysanthemum and ‘Yoauburn’ differed         slightly in ray floret color as plants of ‘Yoauburn’ had ray         florets that were tinged with red.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Leamington, Ontario, Canada during the late spring in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial pot-type Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 24° C., night temperatures ranged from 15° C. to 17° C. and light levels ranged from 4,000 to 6,000 foot candles. Four unrooted cuttings were directly stuck in 15-containers, exposed to long day/short night conditions, and pinched about two weeks later. One week after the pinch, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description had been growing for eleven weeks and were grown as spray-types. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
